Dynamic negative-pressure thoracotomy operating cabin of simulating pectoral cavity

Abstract

The invention is concerned with simulation thorax dynamic negative pressure chest opening Operating Compartment, relating to box, press adjuster, gas tube and airproof connector. The box has upper, middle and down segments and the joint area of the down and middle segments at the front and back ends of the box have holes for neck and down abdomen. The down and middle segments of shell at left and right side of box and the joint area of the middle and upper segments of shell have holes for upper limbs to keep the lung organization take air exchange in primary manner when the thorax of body is open. It avoids forming gas chest of lung organization when the pleura cavity connecting with environment and the pulmonary collapse and pulmonary atelectasis formed by the disappearance of the negative press to pleura cavity, and avoids the damnification of windpipe of sickness for intubatton. The sick can renew as quickly as possible in low-grade anesthetic with few secretion of breath path and keep the function of ventilating.

Description

technical field [0001] The invention relates to a medical instrument for surgical thoracotomy, in particular to a thoracotomy operating cabin under dynamic negative pressure simulating chest cavity. Background technique [0002] At present, surgical treatment of chest diseases such as lung cancer and esophageal cancer requires general anesthesia to make the patient unconscious and spontaneous breathing disappears, and then perform tracheal intubation through the oral cavity, connect the anesthesia machine through the tracheal intubation, and assist breathing through pressurized ventilation; Put the operation position, after disinfection, laying sterile surgical drapes and other preparations, the thoracotomy can be performed. This technology has been maturely used for about 60 years, and can solve the problems of most patients. Its disadvantages are: ① Regardless of the size of the operation or whether it is complicated or not, the degree of anesthesia is relatively deep, and...

Problems solved by technology

This technology has been maturely used for about 60 years, and can solve the problems of most patients. Its disadvantages are: ① Regardless of the size of the operation or whether it is complicated or not, the degree of anesthesia is relatively deep, and the amount of anesthetic drugs is large, which is harmful to the liver, kidney, and brain of the patient. There is certain damage to the cells, and patients with poor liver and kidney function cannot tolerate it, especially for adolescents.
